Be it known that I, EDWARD F. KUN/Urn, n citizen of the United Stntes, residing in Jer sey (lity, in. the county. of Hudson :ind Starte of ew Jersey, have invented certain new end useful Improvements in Type-VVriting ltlzichines, of which the following is e specifi.- cstion.

This invention relntesto the ribbon mechnnisin of type-writing machines, and pertieulerly to means for bringing into use different colors of ribbon at will. Y n

I provide two or more seperate ribbons of different colors and movable independently of one another to cover the printingpoint. In the preferred form of the invention the ribbons are superposd or placed one in front of another in iront of the plsten and means are provided for causing either ribbon to cover and uncover the printing-point during the type-strokes, while the other ribbonremeins idle. I illustra-ite my invention as applied to the welbknown ""Illlderivoorl" 'front-strike Writing-machine, in which spools Carrying the usuel ribbon nre mounted upon vertionl axes one at eneh side of the printing-point infront of the platen. Behind seid ribbon I stretch n. short ribbon of red or other special color, whieh is wound by moons ol spools plz'ioed et The short special ribbon may inlsome enses be endless, ond in such acess' two other spools are placed et the iront of the-machine, so that the endless ribbon winds around four s .pools and incloses the usuel ribbon end its spools. Winding means ere provided for, the

endless ribbon, end I also provide en indil vi duel carrier or vibrator for eooh ribbonone perrier in front ol the other` 'Seid eorriers ere shown movable up and down by ineens of levers. The letter may be substantially like those commonly used inthe Underwood meohine sind may bermounted side by side, either lever being'celled lnto operation at the type-strolres The lever-operating mechanismincludes the usuel universel-ber frame, which reeiproc'.z.les :it oech type-stroke. Upon seid reciprocating member I mount actuators, ono for each ol' said ribbon-vibrating levers, sind ootuetors being shiftnble to engage either one or the other lever. Means m Upon the front side of a revoluble-plnteri l strike types 2, mounted upon typebe'rs 3, the latter being operated. byu right levers'll, connected to key-levers 5. ,n ront of the pla-ten is the usuel ribbon 5,' winding beck and forth upon spools 7 3, the letter mounted l on' vertical shafts 9 l0, provided with pinions 11, meshing with p inions 1 2, the letter rigidly connected to rntchet-wheels 13, operated by pnwls 14, the latter pivoted upon rock-arms 15,iixed upon e rook-shaft 16, on :1 -rm 17, and engaging with the lutter is e. roule nrm 18, extending rightrooking frame 19, to which is pivoted et 20 ears formed upon the rear end of e. horiH zontnl table or reciprocating frame 21.the latter hrzving fixed upon. its front portion a; segmental universel ber 22 engaging the typebztrs. As so fair described the parts are in common use upon seid Underwood machine. Seid ribbon 6 is three-ded through en upstnnding carrier 23, loosely pivoted et 24 to the front end of o. lever 25, which is pivoted. upon o should er-screw 2G,` the lot-ter threaded into n brochet 27,1ixed upon the reer side of s horizontal shiftfreil 28. Seid lever 25 has en forwardly from` en upl' erin 29 extending up from seid pivot 26 and l provided with n 'laterally-proj ecting `pin 30, whereby the lever is` operated during the buckwerd-nud-forward* movement of seid universel-bnr fiume 2l in n 1n :inner presently to be explain ed.

In rear of the moin ribbon 6 I stretch n. l

supplemental ribbon 31, of red or other special color, which. extends between spools 32 33, pivoted et the extreme sides of the me.- ehine, so that the spools 7 8 lio between seid spools 32 33. The letter, it will be under?, stood, may be of any usuel or ordinary typel end may be provided with any suitable or ordinary mechanism for winding the ribbon back and forth between them independently of the spools 7 8. Since, however, the special IOO ` attached ribbon 6.

ribbon is' infrequently used,.it is not always necessary to provide a long ribbon, and for convenience I illustrate in this instance a short ribbon, which I make endless. Spools 34 35 are mounted in front of the spools 7 8 and the ribbon 31 is carried therearounchas seenat Fig. 1, so that said ribbon 31 completely incloses or surrounds the spools 7 8 with their The ribbon 31 will be kept taut by means of a spring 35, which is connected at one end to a fixture and at the kother end to a lever 36, upon which the spool 34 is pivoted, so that the latter is forced out orimedreetion to tighten the ribbon 31.

The s ecial ribbon may be caused to feed back and forth by means of a bevel-pinion 37 on the spool-shaft 9, meshing with a bevelgear'38u on a horizontal shaft 39, which is connecte by .bevel-pinions 39IL and 32*l with the spoo 32. During the winding of the poolf? the spooll 32 is caused torotate in one rection, .while during the unwinding of spool '7 the s 00132 is turnedin the opposite d1rec-' tion, t will be understood t at spool 33 will. be connected tospool-shaft incase it is desired not to use an endless ribbon, but to coil the ribbon back and forth upon fthe spools 32 and 33.

The ribbon 31 is threaded through a ribboncarrier 40, mounted directly behind the carrier 23 and having ears 41 tol embrace a fixed vertical guide 42, which lin said inachine is the ty e-guiding post. Said ears 41, it will be understood, also confine thefcarrier 23 against lateral displacement. The ribbonca11ie1s are guided between said type-post 42 and a iixed abutment 43, a

spring 44being provided upon. the carrier 4()- for pressing both carriers lightly forward against saidD post 42. The carrier 40 is pivoted at its lower end to a lever 45, similar to the lever and `alongside thereof and pivoted u on the shoulder 26 and having an upwar ly-extended arm 4 6, provided with a projecting Y in 47, whereby it is operated..

It will e seen that the ribbon-guiding pins a of the carrier 40 are set in line with the forked main portion of said carrier to correspond with t e direction taken by the ribbon 51 which extends substantially straight across the machine, while the pins 23a of the front carrier 23 are set forward ot' the fork of said carrier to correspond with the forward and outward direction taken by the ribbon ofthe spools 7 8. The pins 40*L are thus well separated from the pins 23, and the carriers move freely up and down independently. of one another.

"Upon an u standing bracket 48, secured upon he tab e 21 by means of screws 49, I

mount a pair of similar actuators 51, having deep vertical slot-s 52 53 to eugage', res ectively, the projecting lever-p2us 47 30.

aid actuatorsare preferably integral, being formed upon. the ends of a vertical plate 54,

shiftable along the bracket 48 and being held upon said plate by shoulder-screws 55, which are inserted with a horizontal slot 56 in said vertical late 54, said slot enabling the actuators to e shifted or adjusted hori- Zontally across the reciprocating table 21, whereby either actuator 50 or 51 may engage its associated lever-pin 47 .or 30, so as to vibrate either lever-45 or 25, and hence to throw up either ribbon 31 or 6 to cause the saine to cover the printingoint during the operation of the types, whi ev the other ribbon remains idle. At Fig. 1 the actuator 50 is shown in engagment with the lever-pin 47, and the lever is elevated. The arm 29 of the other lever rests against astop 57, fixed upon the shift-rail 58, vsaid stopv serving for beth levers when they are idle.

The necessary shifting of the actuators is effected by a link 59, pivoted at 60 to an ear formed upon the actuator member and eX- tending toward the right-hand side of the machine, being there pivoted at 61 to a bellcrank 62 and vibrating idly about said pivot 61 during the backward and forward recipro cations of the table 21.` From the bell-crank extends forwardly a link 63 to a nger-lever or bell-crank 64, mounted at the front of the machineover the keyboard. By raising the lever64 the link 63 is thrown back, the bell-l crank 62 vibrates,'the link 59 is thrown to thel left, the actuator 50V is shifted out of engagrnent with the pin 47, and the actuator -51 is shifted into engagement with the pin 30, "so that the lever 25 will thereafter be vibrated during the typestrokes and the ribbon 6 thrown upto cover the rintingpoint, while the ribbon 31 remains i le. tain the actuators in .either position, I provide a spring-detent 65 upon the framework 66 to engage notches 67, formed upon the bell-crank 62.

It is usual in said Underwood machine to shift the platen up, as at l, Fig. 3, to enable the upper-case characters to print. For Vthis ur ose a shifting frame is provided, of whic '1 t e shift-rail 28 forms a part. The platen 1 is journaled upon a platen-frame, (not shown,) which has a roll 68 to run upon said shift-rail 28. The latter Iis shifted up to 28a, Fig. 3, at the case-shifting o eration, and' with it rise the bracket 27, the levers 25 and 45, and the ribbon-carriers 23 and 40, together with the ribbons carried thereby, the deep vertical slots 52 'and `53 in the ri bon-actuators accommodating the up-anddown shift movement ofv the' lever-pins 47 30. Thus the operation of causing either ribbon to cover the printing-point atv the typestrokes is carried on the same whether the platen is shifted up or down.
